Mechanical Design Engineer (Structures) Level 2

singularity-defense; Gardena (CA); On-site; USD 90,000 - 130,000; Full time

Job summary

singularity-defense in Gardena, CA is seeking a mechanical design engineer to design, prototype, analyze, test, and develop manufacturing processes for ground systems used in rocket/missile launch. You will own system architecture from conception to integrated testing.

The role emphasizes 3D CAD modeling in SOLIDWORKS, GD&T, and collaboration with manufacturing to enable high-rate, high-yield production while managing large assemblies and fielding rugged designs for aerospace environments.

Qualifications

• Bachelor’s or Master’s degree in mechanical engineering or a related technical discipline.
• 4+ years of professional experience in mechanical design and analysis.
• 3+ years of hands-on project experience developing manufacturing processes.
• Proficient in 3D CAD (SOLIDWORKS preferred).
• Familiarity with sheet metal design, welded structures, and vehicle systems.
• Ability to manage large assembly models and drawings.
• Solid understanding and application of GD&T, mechanical engineering fundamentals, structural analysis, and failure modes of complex mechanical systems.
• Prior ownership of a complex component or assembly from initial design through medium-to-high-volume production ramp.
• Familiarity with manufacturing processes and how to design for manufacturability.
• Exposure to a variety of production machinery, industrial sensors, and equipment (motion systems, dispense systems, temperature controllers, laser distance sensors, injection molders, die casters, etc.).
• Self-motivated with strong organizational, written, and oral communication skills.

Responsibilities

• Design structures and ground systems integral to the launch and control of flight vehicles.
• Take ownership of the design through the manufacturing process including basic structural analysis, process development, and defining validation requirements.
• Co-develop product requirements through trade studies to drive optimization at the system level.
• Create intricate and detailed models and engineering drawings in SOLIDWORKS.
• Conduct rigorous testing and iteration cycles to ensure reliability and robust performance across all environments and operational scenarios.
• Continuously develop manufacturing processes to achieve high-rate, high-yield, and dependable production.
• Establish and manage an effective product lifecycle, from supply chain sourcing through final assembly and integration, balancing cost efficiency, production complexity, and quality standards; closely coordinate with partner teams to develop and operate an optimized in-house manufacturing line.
